It sounds like a cortado, though that is usually an equal volume of steamed milk, not frothed. Those have been popular in Spain for a long time, though that doesn’t really answer your question about Buenos Aires.
Coffee
☕ - The hot beverage that powers the world!
Coffee gadgets - It's always great to learn about new gadgets. Please share your favorite hardware or full setups. It might inspire newcomers to experiment!
Local businesses - Please promote your local businesses. If you are not the owner of the business you are promoting, kindly ask the owner if it's okay. It would be great if the business has a physical store to include an exterior or interior shot.
They're similar in that they both aim for equal ratios of milk to coffee, but the Magic is explicitly a double ristretto rather than a single espresso.
Though the similarity (cortado is popular in Buenos Aires too) could explain why the magic is popular. Though it still leaves me curious about how it came to be so prevalent.
That is going to be a very strong cup of coffee. A ristretto is a triple shot! I used to get macchiato ristretto in an even smaller cup and it was yum yum buzz buzz.
A ristretto is the same amount of ground coffee as an espresso, but with only half the water drawn over it. It's not a triple shot, but a double ristretto is definitely stronger than a single espresso shot
